Abstract (en)
[origin: WO2016034487A1] The invention relates to a method for operating a machine plant (1) having a shaft train (2), with the steps of: a) determining, computationally, the harmonic frequency of at least one torsional vibration mode of the shaft train and determining, computationally, the mechanical stresses of the shaft train arising during a vibration period of the torsional vibration mode; b) determining in each case a correlation for each torsional vibration mode between a first stress amplitude, which arises at a position of the shaft train that carries a risk of the formation of stress damage, and a second stress amplitude, which arises at a measurement location (7 to 11) of the shaft train, using the stresses determined computationally for the respective torsional vibration mode; c) establishing a maximum first stress amplitude for the position; d) establishing, using the correlation, a maximum second stress amplitude, corresponding to the maximum first stress amplitude, for the measurement location; e) measuring, at the measurement location and over time, the stress of the shaft train while the shaft train is rotating; f) determining, from the measured stress, a stress amplitude at each harmonic frequency; g) emitting a signal in the event that, at one of the harmonic frequencies, the stress amplitude, determined from the measured stresses, reaches the maximum second stress amplitude.
